The Mitsubishi Lancer Evolution is known for its performance and tuning potential. One of the most effective upgrades for enhancing throttle response and engine performance is the installation of individual throttle bodies (ITBs). In this article, we will guide you through the step-by-step installation of GReddy Individual Throttle Bodies on a Mitsubishi Lancer Evolution.
Tools and Materials Required
- GReddy Individual Throttle Bodies Kit
- Socket set and ratchet
- Torque wrench
- Screwdrivers (flathead and Phillips)
- Wrenches
- Vacuum hose and clamps
- Throttle body gasket
- Intake manifold gasket
- Fuel line disconnect tool
- Shop towels
- Safety glasses
Preparation
Before starting the installation, ensure that you have all the necessary tools and materials ready. Follow these preparation steps:
- Disconnect the negative battery terminal to prevent any electrical shorts.
- Remove any engine covers or components obstructing access to the intake manifold.
- Ensure the engine is cool to avoid burns during installation.
Removing the Stock Throttle Body
To install the GReddy ITBs, you must first remove the stock throttle body. Follow these steps:
- Remove the intake duct connected to the throttle body.
- Disconnect the throttle position sensor (TPS) and any other electrical connectors.
- Loosen and remove the bolts securing the throttle body to the intake manifold.
- Carefully lift the throttle body off the manifold and set it aside.
Installing the GReddy Individual Throttle Bodies
With the stock throttle body removed, you can now install the GReddy ITBs. Follow these instructions:
- Place the new throttle body gasket onto the intake manifold.
- Align the GReddy ITBs with the gasket and intake manifold.
- Secure the ITBs with the provided bolts, tightening them to the manufacturer’s specifications using a torque wrench.
- Reconnect the throttle position sensor and any other electrical connectors.
Connecting the Intake System
After installing the ITBs, you need to connect the intake system properly:
- Attach the intake duct to the new throttle bodies.
- Ensure all clamps are tight and secure.
- Check for any vacuum leaks by inspecting hoses and connections.
Reconnecting Fuel Lines
Next, you will need to reconnect the fuel lines. Follow these steps carefully:
- Use the fuel line disconnect tool to detach the fuel lines from the stock throttle body.
- Attach the fuel lines to the new ITBs, ensuring a secure fit.
- Check for any leaks by turning the ignition on without starting the engine.
Final Checks and Testing
Once everything is connected, it’s crucial to perform final checks:
- Double-check all connections and bolts for security.
- Reconnect the negative battery terminal.
- Start the engine and let it idle to ensure proper operation.
- Listen for any unusual noises and check for leaks.
Tuning Your Mitsubishi Lancer Evolution
After installing the GReddy ITBs, tuning your engine is essential to maximize performance:
- Consider using a standalone engine management system or a reflash to optimize air-fuel ratios.
- Consult with a professional tuner to achieve the best results.
- Monitor engine performance and make adjustments as necessary.
Conclusion
The installation of GReddy Individual Throttle Bodies on a Mitsubishi Lancer Evolution can significantly enhance performance and throttle response. By following this step-by-step guide, you can successfully complete the installation and enjoy the benefits of improved engine dynamics. Always remember to tune your vehicle for optimal performance and safety.
